LA vs Magnum crankshaft

Well, I've got a magnum that spun a rod bearing and took out the crank. Otherwise it looks good. Also have a 70's LA 360 crankshaft the looks like it just needs a quick polish.

So if I used the magnum pistons, rods, damper and flex plate with the LA crankshaft, will it run as is, or be out of balance?
